Comprehensive Geriatric Assessment in the Emergency Department: A Prospective Cohort Study of Process, Clinical, and Patient-Reported Outcomes

Background

This study aimed to explore the process, clinical, and patient-reported outcomes of older adults who received an interdisciplinary Comprehensive Geriatric Assessment (CGA) in the emergency department (ED) over a six-month period after their initial ED attendance.

Patients and Methods

A prospective cohort study recruited older adults aged ≥65 years who presented to the ED of a university teaching hospital in Ireland. Baseline assessment data comprising a battery of demographic variables and validated indices were obtained at the index ED attendance. Telephone interviews were completed with participants at 30- and 180-day follow-up. The primary outcome was incidence of hospital admission following the index ED attendance. Secondary outcomes included participant satisfaction, incidence of functional decline, health-related quality of life, incidence of unscheduled ED re-attendance(s), hospital (re)admission(s), nursing home admission, and death.

Results

A total of 133 participants (mean age 82.43 years, standard deviation = 6.89 years; 71.4% female) were recruited; 21.8% of the cohort were admitted to hospital following the index ED attendance with a significant decline in function reported at hospital discharge (Z = 2.97, p = 0.003). Incidence of 30- and 180-day unscheduled ED re-attendance was 10.5% and 24.8%, respectively. The outcome at the index ED attendance was a significant predictor of adverse outcomes whereby those who were discharged home had significantly lower odds of multiple adverse process outcomes at 30- and 180-day follow-up, and significantly higher function and health-related quality of life at 30-day follow-up.

Conclusion

While this study was observational in nature, findings suggest CGA in the ED may improve outcomes by mitigating against the adverse effects of potentially avoidable hospital admissions and focusing on a longitudinal approach to healthcare delivery at the primary-secondary care interface. Future research should be underpinned by an experimental study design to address key limitations in this study.

The autism spectrum disorder risk gene NEXMIF over-synchronizes hippocampal CA1 network and alters neuronal coding

Mutations in autism spectrum disorder (ASD) risk genes disrupt neural network dynamics that ultimately lead to abnormal behavior. To understand how ASD-risk genes influence neural circuit computation during behavior, we analyzed the hippocampal network by performing large-scale cellular calcium imaging from hundreds of individual CA1 neurons simultaneously in transgenic mice with total knockout of the X-linked ASD-risk gene NEXMIF (neurite extension and migration factor). As NEXMIF knockout in mice led to profound learning and memory deficits, we examined the CA1 network during voluntary locomotion, a fundamental component of spatial memory. We found that NEXMIF knockout does not alter the overall excitability of individual neurons but exaggerates movement-related neuronal responses. To quantify network functional connectivity changes, we applied closeness centrality analysis from graph theory to our large-scale calcium imaging datasets, in addition to using the conventional pairwise correlation analysis. Closeness centrality analysis considers both the number of connections and the connection strength between neurons within a network. We found that in wild-type mice the CA1 network desynchronizes during locomotion, consistent with increased network information coding during active behavior. Upon NEXMIF knockout, CA1 network is over-synchronized regardless of behavioral state and fails to desynchronize during locomotion, highlighting how perturbations in ASD-implicated genes create abnormal network synchronization that could contribute to ASD-related behaviors.

A Physiotherapy-Led Transition to Home Intervention for Older Adults Following Emergency Department Discharge: A Pilot Feasibility Randomised Controlled Trial (ED PLUS)

Background

Older adults frequently attend the emergency department (ED) and experience high rates of subsequent adverse outcomes including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. Our aim was to evaluate the feasibility of a physiotherapy-led integrated care intervention for older adults discharged from the ED (ED PLUS).

Patients and Methods

Older adults presenting to the ED of a university teaching hospital with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED PLUS. ED PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient's home. Feasibility and acceptability were assessed quantitatively and qualitatively. All clinical and process outcomes were assessed by a research nurse blinded to group allocation. Data analyses were primarily descriptive.

Results

Twenty-nine participants were recruited indicating a 67% recruitment rate. At 6 months, there was 100% retention in the usual care group, 88% in the CGA group and 90% in the ED PLUS group. ED PLUS participants expressed positive feedback, and there was a trend towards improved function and quality of life and less ED revisits and unscheduled hospitalisations in the ED PLUS group.

Conclusion

ED PLUS bridges the transition of care between the index visit to the ED and the community and is feasible using systematic recruitment strategies. Despite recruitment challenges in the context of COVID-19, the intervention was successfully delivered and well received by participants. There was a lower incidence of functional decline and improved quality of life in the ED PLUS group.

Trial Registration

The trial was registered in Clinical Trials Protocols and Results System as of 21st July 2021, with registration number NCT04983602.

Perceived policy-related barriers to palliative care implementation: a qualitative descriptive study

Background

Ethiopia has a national palliative care guideline, and palliative care is explicitly recognised in the country's healthcare policy and health sector transformation plans. However, palliative care is not fully delivered in the regional public hospitals and primary health care units.

Objective

This study explores perceived policy barriers to deliver palliative care services in rural and regional healthcare settings, which primary healthcare units largely serve.

Design

Face-to-face interviews were conducted in a rural region of Ethiopia.

Methods

Forty-two participants were recruited from a variety of health settings including primary, secondary and tertiary levels across the region. Interviews were conducted with policymakers from the regional health bureau, pharmacists, medical doctors, health officers (clinical officers) and nurses, including chief nursing officers in leadership roles at all levels of healthcare institutions. Data analysed using thematic analysis.

Results

Participants described several barriers related to healthcare policy, including lack of government priority and focus on palliative care; lack of health professionals' awareness of the national palliative care plans and guidelines; and lack of palliative care integration into the existing healthcare system and the national budget. Participants remarked that palliative care services in the region were mainly limited to HIV patients, often managed with external support and, hence unsustainable.

Conclusions

Policy priority and focus is a fundamental component for the provision of palliative care because lack of focus and support from the government have led to inadequate access to palliative care for all in need. Hence, as participants suggested, palliative care should be integrated into all healthcare levels, particularly into the primary health care units and the health extension programme, to facilitate health extension workers to support millions living in rural areas.

Early Supported Discharge for Older Adults Admitted to Hospital with Medical Complaints: A Qualitative Study Exploring the Views of Stakeholders

Introduction

Early supported discharge (ESD) is well established as a model of health service delivery for people with stroke. Emerging evidence indicates that ESD also reduces the length of stay for older medical inpatients. There is a dearth of evidence exploring the views of stakeholders on ESD as a model of care for older medical inpatients. The overall aim of this study is to explore the views and perceptions of older adults, family carers and healthcare professionals on the potential role of ESD for older adults admitted to hospital with medical complaints.

Methods

Purposeful sampling was used to recruit older adults and family carers for interview. For Healthcare Professionals (HCPs), snowball purposeful sampling was used. Phone interviews took place following a semi-structured interview guide. Focus groups were moderated by A-MM. Braun and Clarke's approach to thematic analysis was used. Ethical approval was granted by the HSE Mid-Western Area Regional Ethics Committee in November 2021 (REC Ref. 096/2021).

Results

Fifteen HCPs took part across three focus groups, with six older adults and two family members participating in one-to-one interviews. Three themes were identified: 1. Pre-ESD experiences of providing and receiving older adult inpatient care, 2. Navigating discharge procedures from acute hospital services, 3. A vision for more integrated model of care and a medical ESD team.

Discussion

This study provided insight into the current discharge experiences of older adult care in the acute setting, the potential role for ESD in this population and the key factors that would need to be considered for the running of an ESD service for older adults admitted to hospital with medical complaints.

Conclusion

This research highlights the barriers and facilitators to ESD for older medical inpatients from the perspectives of key stakeholders. Given the adverse outcomes associated with prolonged hospital stay, these findings will help inform the development of a feasibility trial, examining patient and process outcomes for older adults admitted to hospital with medical complaints who receive an ESD intervention.

Comprehensive geriatric assessment in older people: an umbrella review of health outcomes

BACKGROUND

Comprehensive geriatric assessment (CGA) has been in use for the last three decades. However, some doubts remain regarding its clinical use. Therefore, we aimed to capture the breadth of outcomes reported and assess the strength of evidence of the use of comprehensive geriatric assessment (CGA) for health outcomes in older persons.

METHODS

Umbrella review of systematic reviews of the use of CGA in older adults searching in Pubmed, Embase, Scopus, Cochrane library and CINHAL until 05 November 2021. All possible health outcomes were eligible. Two independent reviewers extracted key data. The grading of evidence was carried out using the GRADE for intervention studies, whilst data regarding systematic reviews were reported as narrative findings.

RESULTS

Among 1,683 papers, 31 systematic reviews (19 with meta-analysis) were considered, including 279,744 subjects. Overall, 13/53 outcomes were statistically significant (P < 0.05). There was high certainty of evidence that CGA reduces nursing home admission (risk ratio [RR] = 0.86; 95% confidence interval [CI]: 0.75-0.89), risk of falls (RR = 0.51; 95%CI: 0.29-0.89), and pressure sores (RR = 0.46; 95%CI: 0.24-0.89) in hospital medical setting; decreases the risk of delirium (OR = 0.71; 95%CI: 0.54-0.92) in hip fracture; decreases the risk of physical frailty in community-dwelling older adults (RR = 0.77; 95%CI: 0.64-0.93). Systematic reviews without meta-analysis indicate that CGA improves clinical outcomes in oncology, haematology, and in emergency department.

CONCLUSIONS

CGA seems to be beneficial in the hospital medical setting for multiple health outcomes, with a high certainty of evidence. The evidence of benefits is less strong for the use of CGA in other settings.

Effectiveness of acute geriatric unit care on functional decline, clinical and process outcomes among hospitalised older adults with acute medical complaints: a systematic review and meta-analysis

Background

the aim of this systematic review and meta-analysis was to update and synthesise the totality of research evidence on the effectiveness of acute geriatric unit (AGU) care for older adults admitted to hospital with acute medical complaints.

Methods

MEDLINE, CINAHL, CENTRAL and Embase databases were systematically searched from 2008 to February 2022. Screening, data extraction and quality grading were undertaken by two reviewers. Only trials with a randomised design comparing AGU care and conventional care units were included. Meta-analyses were performed in Review Manager 5.4 and the Grading of Recommendations, Assessment, Development and Evaluations framework was used to assess the certainty of evidence. The primary outcome was incidence of functional decline between baseline 2-week prehospital admission status and discharge and at follow-up.

Results

11 trials recruiting 7,496 participants across three countries were included. AGU care resulted in a reduction in functional decline at 6-month follow-up (risk ratio (RR) 0.79, 95% confidence interval (CI) 0.66–0.93; moderate certainty evidence) and an increased probability of living at home at 3-month follow-up (RR 1.06, 95% CI 0.99–1.13; high certainty evidence). AGU care resulted in little or no difference in functional decline at hospital discharge or at 3-month follow-up, length of hospital stay, costs, the probability of living at home at discharge, mortality, hospital readmission, cognitive function or patient satisfaction.

Conclusions

AGU care improves clinical and process outcomes for hospitalised older adults with acute medical complaints. Future research should focus on greater inclusion of clinical and patient reported outcome measures.

746 VALIDITY OF THE CARER DIRECTED NEEDS ASSESSMENT IN DEMENTIA (CANDID) FOR USE IN ADVANCED STAGE DEMENTIA CARE

Introduction

End of life care for people dying of dementia and their carer/s is a growing area of importance. Unmet needs are coming amongst this group. A tool to identify the needs of this person-carer dyad is a necessary component for providing this care. The aim of this project was to determine the validity of a new tool, the CArer directed NeeDs assessment In Dementia (CANDID), which was developed for use in a randomised trial of end of life dementia care.

Method

Face validity of CANDID was assessed by an expert panel. A narrative review of the literature to evaluate existing tools available for assessing the needs of carers of people with advanced stage dementia was conducted. A sample of ten trial participants independently completed CANDID and the Carer Specific Needs Assessment Tool (CSNAT), which was selected as the reference tool based on the narrative review. The results from CANDID and CSNAT were compared to assess criterion validity. Participants also completed an evaluation survey to determine which tool they preferred, and why. Responses were compared qualitatively and quantitatively.

Results

CANDID has good face validity. There were insufficient participant numbers to establish criterion validity. The majority (n = 8) of participants preferred CANDID. Participants described a preference for a face to face tool with more specific questions.

Conclusion

Participant carers of people dying of dementia in this trial setting preferred a face to face evaluation of needs. Preliminary results from this study suggest that CANDID has face and content validity, and shows promise for criterion validity.

Impact of assessment and intervention by a health and social care professional team in the emergency department on the quality, safety, and clinical effectiveness of care for older adults: A randomised controlled trial

BACKGROUND

Older adults frequently attend the emergency department (ED) and experience high rates of adverse events following ED presentation. This randomised controlled trial evaluated the impact of early assessment and intervention by a dedicated team of health and social care professionals (HSCPs) in the ED on the quality, safety, and clinical effectiveness of care of older adults in the ED.

METHODS AND FINDINGS

This single-site randomised controlled trial included a sample of 353 patients aged ≥65 years (mean age = 79.6, SD = 7.01; 59.2% female) who presented with lower urgency complaints to the ED a university hospital in the Mid-West region of Ireland, during HSCP operational hours. The intervention consisted of early assessment and intervention carried out by a HSCP team comprising a senior medical social worker, senior occupational therapist, and senior physiotherapist. The primary outcome was ED length of stay. Secondary outcomes included rates of hospital admissions from the ED; hospital length of stay for admitted patients; patient satisfaction with index visit; ED revisits, mortality, nursing home admission, and unscheduled hospital admission at 30-day and 6-month follow-up; and patient functional status and quality of life (at index visit and follow-up). Demographic information included the patient's gender, age, marital status, residential status, mode of arrival to the ED, source of referral, index complaint, triage category, falls, and hospitalisation history. Participants in the intervention group (n = 176) experienced a significantly shorter ED stay than the control group (n = 177) (6.4 versus 12.1 median hours, p < 0.001). Other significant differences (intervention versus control) included lower rates of hospital admissions from the ED (19.3% versus 55.9%, p < 0.001), higher levels of satisfaction with the ED visit (p = 0.008), better function at 30-day (p = 0.01) and 6-month follow-up (p = 0.03), better mobility (p = 0.02 at 30 days), and better self-care (p = 0.03 at 30 days; p = 0.009 at 6 months). No differences at follow-up were observed in terms of ED re-presentation or hospital admission. Study limitations include the inability to blind patients or ED staff to allocation due to the nature of the intervention, and a focus on early assessment and intervention in the ED rather than care integration following discharge.

CONCLUSIONS

Early assessment and intervention by a dedicated ED-based HSCP team reduced ED length of stay and the risk of hospital admissions among older adults, as well as improving patient satisfaction. Our findings support the effectiveness of an interdisciplinary model of care for key ED outcomes.

Strategies used to establish palliative care in rural low- and middle-income countries: an integrative review

Globally, 40 million people need palliative care; about 69% are people over 60 years of age. The highest proportion (78%) of adults are from low- and middle-income countries (LMICs), where palliative care still developing and is primarily limited to urban areas. This integrative review describes strategies used by LMICs to establish palliative care in rural areas. A rigorous integrative review methodology was utilized using four electronic databases (Ovid MEDLINE, Ovid Emcare, Embase classic+Embase and CINAHL). The search terms were: ‘palliative care’, ‘hospice care’, ‘end of life care’, ‘home-based care’, ‘volunteer’, ‘rural’, ‘regional’, ‘remote’ and ‘developing countries’ identified by the United Nations (UN) as ‘Africa’, ‘Sub-Saharan Africa’, ‘low-income’ and ‘middle- income countries’. Thirty papers published in English from 1990 to 2019 were included. Papers were appraised for quality and extracted data subjected to analysis using a public health model (policy, drug availability, education and implementation) as a framework to describe strategies for establishing palliative care in rural areas. The methodological quality of the reviewed papers was low, with 7 of the 30 being simple programme descriptions. Despite the inclusion of palliative care in national health policy in some countries, implementation in the community was often reliant on advocacy and financial support from non-government organizations. Networking to coordinate care and medication availability near-patient homes were essential features of implementation. Training, role play, education and mentorship were strategies used to support health providers and volunteers. Home- and community-based palliative care services for rural LMICs communities may best be delivered using a networked service among health professionals, community volunteers, religious leaders and technology.

Comparison of novel tools with traditional cognitive tests in detecting delirium in elderly medical patients

BACKGROUND

Efficient detection of delirium and comorbid delirium-dementia is a key diagnostic challenge. Development of new, efficient delirium-focused methods of cognitive assessment is a key challenge for improved detection of neurocognitive disorders in everyday clinical practice.

AIM

To compare the accuracy of two novel bedside tests of attention, vigilance and visuospatial function with conventional bedside cognitive tests in identifying delirium in older hospitalized patients.

METHODS

180 consecutive elderly medical inpatients (mean age 79.6 ± 7.2; 51% female) referred to a psychiatry for later life consultation-liaison service with delirium, dementia, comorbid delirium-dementia and cognitively intact controls. Participants were assessed cross-sectionally with conventional bedside cognitive tests [WORLD, Months Backward test (MBT), Spatial span, Vigilance A and B, Clock Drawing test and Interlocking Pentagons test] and two novel cognitive tests [Lighthouse test, Letter and Shape Drawing test (LSD)-4].

RESULTS

Neurocognitive diagnoses were delirium (n = 44), dementia (n = 30), comorbid delirium-dementia (n = 60) and no neurocognitive disorder (n = 46). All conventional tests had sensitivity of > 70% for delirium, with best overall accuracy for the Vigilance-B (78.3%), Vigilance-A (77.8%) and MBT (76.7%) tests. The sustained attention component of the Lighthouse test was the most distinguishing of delirium (sensitivity 84.6%; overall accuracy 75.6%). The LSD-4 had sensitivity of 74.0% and overall accuracy 74.4% for delirium identification. Combining tests allowed for enhanced sensitivity (> 90%) and overall accuracy (≥ 75%) with the highest overall accuracy for the combination of MBT-Vigilance A and the combined Vigilance A and B tests (both 78.3%). When analyses were repeated for those with dementia, there were similar findings with the MBT-Vigilance A the most accurate overall combination (80.0%). Combining the Lighthouse-SA with the LSD-4, a fail in either test had sensitivity for delirium of 91.4 with overall accuracy of 74.4%.

CONCLUSION

Bedside tests of attention, vigilance and visuospatial ability can help to distinguish neurocognitive disorders, including delirium, from other presentations. The Lighthouse test and the LSD-4 are novel tests with high accuracy for detecting delirium.

Benefit of Sequential Audit Cycles in Improving Management of Vitamin D Deficiency in the HIV Infected Paediatric Population

Aims Lifelong HIV infection has an unknown impact on bone health in children. In view of this, we aimed to improve management of vitamin D deficiency. Methods Three audits over 8 years (2009-2017) were performed with interventions introduced intermittently in an effort to improve vitamin D deficiency. The interventions included education, a change in vitamin D dose and brand to increase compliance and a shift to nursing led management. Results The most striking result was the eradication of patients with deficient vitamin D levels (<25nmol/L) in 2017. In 2009 and 2015, 15% and 9% were deficient. In the earlier two studies, only 15% had ‘sufficient’ (>50nmol) vitamin D levels. This increased to 71% in 2017. 10% of patients had levels greater than >120nmol/L, increasing risk of vitamin D toxicity. 67% of patients with insufficient vit D (25-50nmol/L) were prescribed a stat high dose vitamin D (120,000 IU) to help avoid adherence issues. Conclusions Sequential audits along with a shift to nurse led management were the most likely reasons for sustained improvement. Similar projects in all medical departments could improve clinical outcomes.

Impact of early assessment and intervention by teams involving health and social care professionals in the emergency department: A systematic review

Background

Dedicated Health and Social Care Professional (HSCP) teams have been proposed for emergency departments (EDs) in an effort to improve patient and process outcomes. This systematic review synthesises the totality of evidence relating to the impact of early assessment and intervention by HSCP teams on quality, safety and effectiveness of care in the ED.

Methods

A systematic literature search was conducted in April 2019 to identify experimental studies examining the effectiveness of ED-based HSCP teams providing services to adults aged ≥ 18 years old and including two or more of the following disciplines: occupational therapist, physiotherapist, medical social worker, clinical pharmacist, or speech and language therapist. Data extraction and quality appraisal of each study were conducted independently by two reviewers.

Results

Six studies were included in the review (n = 273,886), all describing interdisciplinary Care Coordination Teams (CCTs) caring for adults aged ≥ 65 years old. CCT care was associated with on average 2% reduced rates of hospital admissions (three studies), improved referrals to community services for falls (one study), increased satisfaction (two studies) with the safety of discharge (patients and staff), and with the distribution of workload (staff), improved health-related quality of care (one study). No statistically significant differences between intervention and control groups emerged in terms of rates of ED re-visits, ranging between 0.2% and 3% (two studies); hospital length of stay (one hour difference noted in one study) or mortality rates (0.5% difference in one study). Increased rates of unplanned hospitalisations following the intervention (13.9% difference) were reported in one study. The methodological quality of the studies was mixed.

Discussion

We found limited and heterogeneous evidence on the impact of HSCP teams in the ED, suggesting a reduction in hospital admissions as well as improved patient and staff satisfaction. More robust investigations including cost-effectiveness evaluations are needed.
